(CNN) -- A bombing in eastern Turkey on Monday killed nine soldiers and wounded two others, the state news agency said, citing a provincial governor's office.

A mine exploded near a bridge in the town of Kemah, in Erzincan province, when a military vehicle was going by, according to the Anadolu news agency. It cited the Erzincan provincial governor's office.

There has been no immediate claim of responsibility, but Turkish officials suspect the Kurdistan Workers' Party, or PKK. Turkish troops and PKK guerrillas have been fighting since the 1980s.
